LIQUID-DISPENSING APPARATUS.

SPECIFICATION forming part f Letters Patent N0. 575,446, dated January19, 1897. Application iiled March 2, 1896. Serial No. 581,547. (Nomodel.)

To aZZ whom t may concern: occasions a considerable loss in addition toBe it known that I, FRANK H. TRUMBULL, the delay and annoyance caused bythe nea residentof Palmyra, in the county of Wayne cessity of drawing itoff preparatory to servand State of New York, have invented cering acustomer with that which is better. To 55 tain new and usefulImprovements in Pneuprevent this evil, the pressure above the beer maticFaucets for Ale, Beer, and other Liqin the barrel and above that in thepipe is nids; and I do hereby declare the following to equalized by themeans to be described. be a full, clear, and exact description of the 3denotes afaucet havinga three-way cock. invention, such as will enableothers skilled The parts or conduits of the cock are indi- 6o 1o in theart to which it pertains to make and cated by 4., 5, and G, though theAarrangement use the same. of these may be varied to some extent. VhenThe invention relates to dispensing` liquids, the cock is turned asindicated in Fig. 3, the and particularly ale, beer, wine, and otherfaucet-passage is in free communication with like carbonated beverages;andits object is 'the interior of the barrel through the ports e 6 5 toprovide economical and conveniently-opand 5, the port t being closed,except through erated devices whereby the lpressure in the the faucet tothe open air.

A carbonatedbevbeing such that pressure may be equalized as erage standing for anyconsiderable time in above described, and this and other such like 9 5 apipe becomes stale, and particularly if the arrangements are within theinvention; and, pipe is situated wholly or partly in a Warm further, aseparate cock might be provided room. It is customary to draw such stalefor opening communication between the barbeer and treat it as Waste orotherwise disrel and the draw-off pipe, as indicated in Fig. pose of itin order that customers may be 5, in which ll denotes a cock by whichpipe roo 5o served with a cool lively draft directly from 7, leadingeither directly or mediately to the the barrel. Such disposition ofstale beer barrel, can be putin communication with thev upper end of thedraw-off pipe below the faucet-cock.

More complex devices have been proposed for a purpose having resemblanceto that contemplated herein. My improvement is characterized by acombination, hereinafter pointed out, of a faucet having an automaticdischarge by gravity on the delivery side of the cock, a receptacleholding fluids under pressure, and pipes whereby the closing of theliquid-discharge port of the cock equalizes pressure in the pipes andreceptacle, both the faucet-discharge and the discharge-pipe back of thefaucetscock being emptied of liquid, as set forth.

Having described my invention, what I claim isl. In combination with aholder for a liquid under pressure above the normal, a drawoff pipeextending upwardly from said barrel, a faucet having a discharge-passagecontinuously in or extending below the plane of the faucet and providedwith a cock having ports whereby the draw-off pipe can be alternatelyput in communication with the said horizontal faucet-discharge and witha pipe leading to the barrel above the liquid therein, and means forequaliz'ng the pressure in the barrel and above the liquid in said pipe,said means consisting of a pressure-equalizing conduit connected tocommunicate through the faucet-cock with the barrel whereby the interiorof the barrel above the liquid and the upper portion of theliquid-discharge pipe immediately at the faucet-cock may be made tocommunicate and whereby the dischargeconduits on both sides of thefaucet may be emptied of their liquid contents by a simple manipulationof the cock, substantially as described.

2. In combination with a holder for liquid under pressure above thenormal, a draw-off pipe extending upwardly from said barrel, a faucethaving a discharge-passage continuously in or extending below the planeof the faucet and provided with a three-way cock, a pipe having ahorizontal faucet-discharge conduit and connecting said cock with theupper part of the barrel, a pipe connecting the same cock with thedraw-off pipe, said cock being adapted to simultaneously close thefaucet-discharge and open communication between said pipes through itsports, and a supplementary pipe provided with a cock and connecting thetwo rst-named pipes above the barrel and adjacent the drawoi cock,substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
